A very old guy once told me that he liked a country song about a card game that said this:
"You have to know when to hold them, when to fold them, when to walk away, and when to run."
That kind of wisdom at the moment you need it is nearly impossible to calculate. Simply no one is that smart.
So - One Thing:
A precondition and presupposition: - it is a beautiful natural world with wonderful creatures and people - who are also finite and radically messed up. A mixed-bag, this world.
People will tell the truth, withhold the truth, and lie.
And people will 'act' in times of ethical tension or crisis - (hold them, fold them, walk, run)
Each person will have a priority item, something that is the most important thing for them.
Example - if relationships - then they will act based on the preservation or promotion of that general priority. They will 'know' instinctively in the moment what they should do and do it - tell the truth, withhold the truth, or lie.
Example - if money and status - then they will act based on the preservation or promotion of that general priority. They will 'know' instinctively in the moment what they should do and then do it - tell the truth, withhold the truth, or lie.
One thing. Risk is involved in either case (or whatever fills the priority item - those are just two examples).
Back to the precondition and presupposition that it is a fallen world:
The question can become - Is the priority item a force in opposition to the flow and nature of life? (positive or 'for good')
Or is the priority item a force that goes with the natural flow of life.
